Over the past five seasons—due to the autumn lockout of 2012, the NHL held no preseason games before last season—just under two-thirds of preseason winners have repeated those victorious ways in the regular season.

That 61.3 percent mark is a suggestive, but hardly decisive, statistic with which to weigh training camp's relevance.

If the outlying 2009 campaign is thrown out, however, the number jumps to 66.0 percent and begins to move toward a genuine conclusion.

Moreover, of the 30 preseason division winners over those same five years, 19 qualified for the playoffs the following spring and 11 also took their respective division crowns during the regular season.

The 2010 preseason, in fact, predicted the exact final standings of both the Southeast and Atlantic Divisions.

Nonetheless, the picture painted by those stats may not be as clear as it at first seems to be.

The NHL's flexible preseason oversight allows teams to schedule their own games and therefore play as many as 10 or as few as three matches during September's festivities. Additionally, the inclusion or non-inclusion of simultaneous split-squad games can tilt the standings in various directions.

After all, the last three Stanley Cup champions—Chicago (15-15-5), Los Angeles (16-10-8) and Boston (16-13-5)—all have losing preseason records from 2007 on.

There hardly exists a more convincing argument against the preseason's debated relevance.
